Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701580, here are decompositions:

3 + 8701577 = 8701580
61 + 8701519 = 8701580
73 + 8701507 = 8701580
103 + 8701477 = 8701580
157 + 8701423 = 8701580
271 + 8701309 = 8701580
313 + 8701267 = 8701580
337 + 8701243 = 8701580

Showing the first eight; more decompositions exist.
